Skeptics who said last season that Moscoso's flyball tendencies would not translate well to Coors Field were rightfully vindicated, as Moscoso's painfully low 34.6 groundball percentage yielded a 1.4 HR/9, the highest of his career at any level. Those issues were most amplified in a July outing against the Nationals that saw Moscoso surrender eight runs on eight hits (three homers) in 1.2 innings of mop-up duty. Now that he is with Kansas City, Moscoso has a much better chance to thrive at the relatively neutral Kauffman Stadium, and would seem to be in position to contend for a starting or long relief role with the big club. Moscoso should be further aided by a normalization in BABIP (.378 last season) and an increased strikeout rate (8.5 K/9), but park factors must always be considered when deploying him in your lineup.

2012

Moscoso had a surprisingly effective year in 2011, split between Triple-A Sacramento and Oakland. He fanned 52 batters against just 16 walks in 46.1 innings in the minors, and pitched well at times with the A's when called upon him. His .235 BABIP is unsustainable, of course, and now his flyball tendencies will crush him moving from Oakland to Colorado. His splits tell the story: 0.915 WHIP, 2.42 ERA and 50 hits allowed in 74.1 innings at home; 1.342 WHIP, 4.70 ERA and 42 hits allowed in 53.2 innings on the road. This might not end well.

2010

Moscoso spent most of the year in the minors, split between Double-A Frisco (nine appearances) and Triple-A Oklahoma City (12 appearances), though he surfaced to make 10 appearances in Arlington. Obtained in the offseason from Detroit, Moscoso pitched well at Triple-A. He's been used almost exclusively in relief down in winter ball, making just one start among his 14 appearances. His future is likely in the bullpen, and there are strong strikeout rates in his past that suggest he can be a valued commodity out of the bullpen.

2009

Moscoso, who turned 25 this winter, is behind schedule in his movement through the Detroit system because of injuries. He emerged as a prospect in 2008 posting a 3.12 ERA and a 50:8 K:BB ratio in 34.2 innings at High-A Lakeland before a promotion to Double-A Erie. His 122:21 K:BB ratio in 86.2 innings between the two levels is very impressive. Moscoso's repertoire consists of a fastball that averages around 92 mph with an average curve and a developing changeup. The Tigers traded Moscoso to the Rangers in early December as part of the package for Gerald Laird. He'll begin the year in the minors, but opportunities should become available quickly if he performs.
